Ultrasound is the only physical factor that can perform not only micromassage of tissues, but also individual cells. This is due to the effect of ultrasound, consisting of mechanical micromassage of cells and tissues, thermal absorption of mechanical ultrasonic vibrations of the body tissues with the formation of heat and physicochemical effects.
Ultrasound can be regarded as a kind of physical catalyst of biochemical, biophysical and physicochemical reactions and processes in the body.
Ultrasound therapy in many cases is very effective, it has a pronounced anti-inflammatory, antispasmodic, resolving, trophic, analgesic, fibrinolytic and hyposensitizing effect, stimulates regenerative processes, promotes resorption of adhesions and scars. This is due to the activation of intracellular processes of protein biosynthesis and enzymatic reactions. It is established that the scar tissue, which is formed under the influence of ultrasound, is stronger and more elastic. Ultrasound affects the location of newly formed collagen and contributes to the recovery process: however, it increases the strength of scar tissue.
